Product Description:

The NTM01.1-024-04 is a single-output power supply manufactured by Bosch Rexroth Indramat for the NTM Power Supply Units series. Installed on a control panel rail, it converts standard line voltages into a stabilized 24-volt bus that feeds drives, I/O boards, and sensor chains inside automated cells. The unit is intended for operation at ambient temperatures up to 45 °C, ensuring that motion controllers and logic modules receive a constant DC source even when cabinet temperatures rise during extended duty cycles.

When the mains is set to 115 V, the converter draws 2.2 A; switching the selector to 230 V cuts steady-state draw to 1.2 A. At power-up, it can tolerate an inrush of 32 A without damage to internal rectifiers or fuses. Under nominal conditions, the supply can deliver a continuous output current of 4.2 A, corresponding to an output power of 100 VA at the stated ambient limit. The regulated rail is held at 24 VDC, allowing direct connection to 24-volt actuators and logic circuits while maintaining isolation from the higher-voltage mains side. A separate continuous-current rating applies at the maximum ambient temperature, providing an additional reference for thermal loading.

Mechanical integration is simplified by a DIN 50 mounting clip that locks the housing onto a standard profile without extra brackets. Front-panel trim pot adjustment permits output trimming within a tolerance of ±10%, which is useful when compensating for long cable runs or intentional overvoltage of field devices. The enclosure measures 97 mm wide, 51 mm deep, and 202 mm high, so it occupies a narrow slot on crowded panels while still providing access to terminals and indicators. For applications that must respect average load rather than instantaneous peaks, the thermal current ceiling of 3.8 A helps with fuse selection and heat dissipation planning.
